The short version
- Aerosols are covered by their own flammability classification and labelling rules, under the Aerosol Dispensers Regulations 2009 and the CLP Regulation - "Danger" or "Warning" signal words tied to a specific flammability category, not optional wording.
- Royal Mail bans most aerosols outright, with a narrow exception for toiletry and medicinal aerosols under strict limits - and specifically still bans air fresheners, even though they can look similar to an allowed product.
- Candles have their own designated safety standards - BS EN 15493 for fire safety, BS EN 15494 for warning label format and content - meeting them creates a legal presumption the product is safe.
- CLP chemical labelling only applies to a candle if it genuinely contains hazardous ingredients - not an automatic requirement for every scented candle, but worth checking with a specific supplier rather than assuming either way.
- The general lesson is broader than either product: a "small" add-on category next to a core furniture catalogue often carries its own separate compliance layer a furniture-only shop never had reason to learn.
Aerosols: classification, labelling, and a specific shipping trap
Checked 26 September 2026: aerosol dispensers sold in the UK are covered by the Aerosol Dispensers Regulations 2009, which requires a specific signal word and label elements tied to a product's actual flammability classification under the CLP Regulation - "Danger" for an extremely flammable aerosol, "Warning" for a flammable or non-flammable one, each with its own required label elements. This is not optional wording a seller can simplify; it is tied directly to how the specific product has actually been classified.
The genuinely easy mistake sits with shipping, not labelling: Royal Mail bans aerosols for any purpose other than toiletry or medicinal use - deodorants, body sprays, hairspray, shaving foam, and similar - and even those are limited to 500ml per item, a maximum of two items per parcel, with a required ID8000 label. Air fresheners specifically remain prohibited outright, alongside spray paints and solvents, even though an air freshener can look, to a seller unfamiliar with the specific list, like it should sit in the same allowed category as a permitted toiletry aerosol.
Candles: the standards that create a presumption of safety
Candles sold in the UK are covered by two designated standards worth knowing by name: BS EN 15493, covering fire safety, and BS EN 15494, covering the format and content of a candle's own warning label. Meeting both does not remove a seller's underlying responsibility to sell a genuinely safe product, but it does create a legal presumption that the product is safe with respect to the specific risks those standards cover - the same "presumption of conformity" pattern already true of BS 5852 for upholstered furniture. A candle's label needs to present its warnings clearly and largely non-verbally where genuinely possible, in a format the standard itself specifies precisely, not simply "some safety wording somewhere on the packaging" left to a supplier's own discretion.
Why CLP does not automatically apply to every candle
It is a reasonable assumption that a scented candle, containing fragrance chemicals, must carry CLP hazard labelling the way a genuinely hazardous chemical product would. This is not automatic: CLP labelling is only required if a candle's actual ingredients are genuinely hazardous under the regulation's own criteria - a plain wax candle with a mild, compliant fragrance load may need no CLP labelling at all. The honest answer depends on the specific product's actual formulation, which is a genuine question worth putting directly to a specific supplier rather than assuming either way based on the product simply being scented.
The separate, platform-specific step eBay itself requires in the listing
Checked 27 September 2026, directly against eBay's own guidance on product safety disclosures and hazardous materials labelling: this is a distinct, additional step from the CLP classification and physical labelling covered above, sitting inside the listing tool itself. eBay names "aerosol cans, spray cans" directly on its own list of products requiring hazard information, and the mechanism is built directly into the listing editor - an "Item disclosures" section with a "Hazard information" toggle, where a seller selects at least one hazard statement, an optional signal word (Warning or Danger), and up to four pictograms, all displayed to the buyer on the listing itself before any purchase is made. This is worth knowing as a genuinely separate task from getting the physical product correctly labelled: a supplier's aerosol can be correctly classified and physically labelled under CLP, and the eBay listing selling it can still be missing the matching hazard disclosure inside eBay's own tool, which is its own compliance gap regardless of what the physical product itself already shows.
Why this is really about more than candles and aerosols specifically
The pattern worth taking from both examples is broader than either product: a "small," seemingly easy add-on category sitting next to a core furniture catalogue very often carries its own separate compliance layer that a furniture-only shop never had reason to learn - different standards, different labelling regime, sometimes a completely different shipping restriction that has nothing to do with anything already understood about furniture. Expanding into a genuinely new category is worth treating as its own small research project, not an extension of rules already known from an entirely different kind of product.
A third category worth naming directly, because it sits even closer to a furniture shop's own catalogue
eBay's own list of products requiring hazard information reaches beyond aerosols and cleaning sprays generally - it names "care and cleaning products," "glue & adhesives," and "paints & varnishes" directly, which is worth flagging specifically because these sit much closer to a furniture shop's natural range than candles or air fresheners ever would. A leather cleaner, a tin of wood wax, or a touch-up varnish sold alongside a furniture catalogue as a natural complementary add-on is exactly the kind of product this same hazard-disclosure requirement was written for, and it is easy to overlook precisely because it feels like a small, obvious accessory rather than a "chemical product" in the way an aerosol or a solvent more obviously reads. The same two-part check applies here as everywhere else in this piece: confirm the product's actual CLP classification with the supplier, and add the matching hazard information inside eBay's own listing tool, rather than assuming a small tin of furniture wax falls outside the requirement simply because it does not look like the kind of product the rule was obviously written for.
What to actually ask a supplier before adding either category
For aerosols, the specific question is which purpose the product is genuinely classified under and whether it falls inside a permitted courier's own limits - not an assumption based on how similar it looks to an allowed product. For candles, the specific question is whether the supplier can confirm the product meets BS EN 15493 and BS EN 15494, and whether its fragrance formulation has actually been checked against CLP's hazard criteria rather than simply assumed safe because most candles are. Neither question is unreasonable to put directly to a supplier before listing, and a supplier genuinely unable to answer either one plainly and confidently is itself a useful, honest signal worth taking seriously.
A worked example
A furniture shop considering adding a small range of scented candles and room-fragrance sprays as a complementary add-on: the candles need checking against BS EN 15493/15494 and a genuine, direct question put to the supplier about CLP status; the sprays need checking specifically against Royal Mail's own restricted list, and against whichever alternative courier might actually be used instead, before assuming any courier will simply carry them the way a piece of furniture would without a second thought. Neither check is difficult once it is actually done - the risk sits entirely in assuming a small, simple-looking product needs no separate research at all. A third, easily missed example from the same shop's own range: a small tin of furniture wax added purely as a helpful accessory alongside the sofas and sideboards it is meant to complement needs the same eBay hazard-information toggle completed as the aerosol sprays do, simply because "care and cleaning products" sits on eBay's own list too - a detail genuinely easy to miss precisely because the product feels like an afterthought next to the furniture it was added to support.
Where this stays worth a person's own research
Sellhelm's own product editor keeps a category and its item specifics organised the same way whatever the product actually is, but the specific safety standard, labelling requirement, or shipping restriction that applies to a genuinely new category is not something any listing tool can look up on a seller's behalf - it stays worth its own short, deliberate check before the first order goes out - a few minutes spent confirming a new category's own rules once, at the point of adding it, rather than discovered later as an unwelcome surprise once the product is already live and selling.
Questions people ask
Can I post aerosols through Royal Mail?
Only toiletry or medicinal aerosols such as deodorant or hairspray, under strict limits: 500ml maximum per item, no more than two per parcel, with a required ID8000 label. Aerosols for other purposes, including air fresheners, remain prohibited.
Do scented candles need CLP hazard labelling?
Not automatically - only if the candle’s actual ingredients are genuinely hazardous under CLP’s own criteria. A plain wax candle with a compliant fragrance load may need no CLP labelling at all, but this is worth confirming with the specific supplier.
What standards apply to candles sold in the UK?
BS EN 15493 covers fire safety and BS EN 15494 covers the format and content of the warning label. Meeting both creates a legal presumption the product is safe with respect to the risks those standards cover.
Why do "small" add-on categories need their own research?
Because they often carry an entirely separate compliance layer - different safety standards, labelling rules, or shipping restrictions - that has nothing to do with rules already understood from a shop’s existing core category.
